Font size in custom page template not right after update to WP5.9

Hello and many thanks for helping me with this one:

I updated my test site to WordPress 5.9 and Newspaper 11.4.1 (required plugins are updated as well).

In posts that use an adjusted custom single post cloud template the font size does not equal anymore the one set in the theme panel when block typography is set to 32 in the editor – typography 32 is the default running on my live website that is still WP5.8 and Newspaper 11.3.1.

If I’m in editing mode for a post and change typography to either 15 or even 50, the post font is displayed correctly in preview.

Do I need to adjust any settings? Cache has been cleared after the updates.

Many thanks again

Hello Bettina,

many thanks.
Please find a video here: https://www.screencast.com/t/MBdtBzW0c

The standard setting for typography in the block settings when editing a post (custom post template) is 32.
On the live website: https://www.chillipicks.com (WP5.8/Newspaper 11.3.1) all body text in posts is displayed correctly according to my font settings in theme panel.

After updating my test site https://staging.chillipicks.com to WP5.9 and Newspaper 11.4.1 version (all plugins updated as well) the block text of existing posts is not displayed correctly – too large. I did not change any settings for fonts in the theme panel.

When I edit a post and change the typography from 32 to either 15 or even 50 the preview of the post shows the correct font size for the block text.

Many thanks for you advice on what to do.

P.S. Viewing of the test site is protected by a password (so it’s not scanned by search engines) which I can share in private.

Hello Bettina,
